Electric boiler v gas boiler

I know that you need a gas boiler to be on an outside wall for the flu.  But does that also apply to an electric boiler?

Gas boilers do not need to be on an outside wall.

Likewise I cannot imagine an electric boiler would either, any overpressure vent would need an external outlet but that could go through internal walls or via the loft.

I have an electric water tank inside a cupboard. It is called an unvented hot water cylinder and it has to be fitted by an electrician also  qualified in fitting this type of boiler 

no the cupboard is not on an outside wall

I think I meant the flue must have a way out. Is that the same for electric?

A flue is to remove the fossil fuel combustion waste gasses to outside, what combustion gasses does an electric boiler produce ?

You're making the mistake of assuming others have the same level of knowledge as you. Heaven forbid you ever need to ask a 'silly' question.

Hi, no it’s not got any way out so to speak. It’s like an immersion tank just run on electric and with no covers or jacket on . It’s unvented which I think just means what is says, that no ventilation is required. I think it’s why an electrician with a certified to instal them. With the cylinder and fitting came to about 1200 quid about 5 years ago

Hi. 
No, the electric boiler will not need to be adjacent to an outside wall. 
(Even a gas boiler's flue can run quite some distance to the outside wall or roof, but I get what you mean)
The unvented leccy boiler - or storage cylinder - will most likely require access to a drain, tho', for safety discharge reasons, but that doesn't necessarily mean the 'outside', afaIk. But, a run of 15mm (I think) copper pipe to the outside for this would be the preferred solution. Otherwise it's 'tundish' and 22mm copper to a suitable drain. AfaIk.

What is your situation? What do you currently have, and what do you want?

Bear in mind that leccy = 3 times the cost of gas.

Is it to run central heating or just for how water? If for heating I would avoid as it'll be very expensive to run.

Unvented means that it it is not supplied by a water tank in the roof, but direct from mains water.

I think you actually need a certified ( G3) plumber/heating engineer to fit them, as a number of safety type valves need to be fitted, in case something goes wrong and the water overheats higher than it should, and builds up a dangerous pressure in the cylinder.
An electrician would be needed normally just to complete the installation/wire it up.

. I have an electric boiler because my property is all electric, no gas mains. 

I have electric radiators,, basically electric heaters which are wall mounted and the electrical cylinder for hot water .
hope that makes sense
